<h3>Sentinel-1 SLC to GRD</h3>
<p>
The Toolbox provides a graph which applies processing to a Sentinel-1
SLC product in order to generate a product similar to a GRD product
generated by the IPF. However, the processing applied is not identical.</p><p class="MsoNormal"><span style="" lang="EN-GB">This will includes:</span></p>

<p class="MsoNormal">For the IW and EW GRD products, all the bursts in all

<h3>GRD<br>
</h3>

<p>The GRD Post Processing operator updates
the product type, product name and other fileids in the metadata to make
it a true GRD product. <br>
</p>
<h4>Input <br>
</h4>




<ul>
<li>The input to this operator should be the GRD product generated by the S-1 SLC to GRD operator. <br>
  </li>
</ul>


<h4>Output <br>
</h4>





<ul>
<li>The output of the operator is the same product with the metadata and product name updated. <br>

  </li>
</ul>



<h4>Parameters Used<br>
</h4>





<ul>
